application filed Apr-30,1896. Serial No- 589,'768- (No specimens) To all whom it may concern:

Be it known that we-,.H1LLIARY ELnnmeE,

WAMBAUGH, citizens of the United States, rein the county of Galves- Texas, have. invented a new and useful Composition for the Manufacture of Calcium Sodie Cerbid, of which the following is a specification.

This invention relates'to of calcium sodic carbid; and it has for its jeet to provide a new and useful composition of matter for use in cium sodic carbid.

To this end the main and primary object of the invention is to provide a composition of matter that will eiiect or insure the very rapid reduction and combination of the ingrcdients to form calcium sodic cal-bid on an economical commercial basis.

\Vith these and other objects in view the invention essentially eonsists in a composition of matter composed of seventy-two bushels of quicklime, forty bushels of carbon, four bushels of soda, and one-eighth of a bushel of borax.

The proportions specified are such as are preferably observed in the manufacture of the carbid product, and in the manufacture of this product all of the ingredients are thoroughly pulverized and mixed together, after which the composition is subjected to thc fusing heat of an electric furnace, thereby producing calcium sodie carbid with a trace of borax.

the manufacture the manufacture of cal-- soda and borax by scribed.

An import-ant feature of the present invention is the use of the ingredients soda and borax in combination with the carbon and lime, it being noted that the soda and borax have an actionon the lime similar to a flux or an acid. This action of the soda and borax greatly accelerates the reduction of the lime to metallic calcium,'while.at the same time the soda is reduced to metallic sodium, ed that the carbon readily combines with the metallic vsodium and calcium, thus rapidly forming the calcium sodic'carbid with a trace of borax.

In order to carry out the invention on the most economical basis possible, carbonate of soda or common washing soda is used, but it will be understood that the water of crystallization is expelled from the carbonate of heat before mixing with the other ingredients.

Having thus described the invention, what.

we claim is- A compound for the manufacture of calcium sodic carbid composed of quicklime, carbon, soda, and borax, substantially as de- In testimony our own we have hereto affixed our signatures in thepresence of two witnesses.
